To all 'whom it may concern:

Be it known that l, PAUL E. GLEAsoN, a citizen of the United States, anda resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a certain new and useful Safety-Razor Adjustment; and l dohereby declare the following to be a full, clear,.and eXact descriptionof the invention, such .as vwill enable others skilled in the arttofwhichjit appertains to make and use the same, reference being had tothe accompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

This invention relates to safety Y razors, and particularly to the bladeadjustment of razors of the Gillette type.

With the Gilletteurazor it is possible to adjust the blade edgesrelative to the guard for a light or close shave. It is the practice ofmany men in, using this razor to go over .the face twice-first for alightshave, with the blade edge close to the Second timefor a closeshave,

guard, and the with the blade edge placed a greater extent from theguard.l

Diiiculty lis experienced each time, however; in securing the rightadjustment, or if only one adjustment is used for all shaving, suchadjustment 1s lost each time the blade is reroved from the holder"forthe purpose of cleaning or replacement.

4The object of my invention is the provision, in a razor of the classdescribed, of

simple, eicient and inexpensive means for maintaining the adjustment ofa blade edge holder, and at the same time the holder without disturbingthe position of adjustment of said means, thereby enhancing thepracticability and commercial value of razors of this character. Furtherobjects and advantages of the invention will be apparent from thefollowing detailed description thereof.

The invention lspfully described in the followingy specification, andwhile, in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment only thereof is illustrated in theaccompanying drawings, in which,'-

Figure 1 is an elevation of a razoi` of the FGillette type embodying myinvention.

Fig. 2' is a similar view thereof with the blade holder part in section,and Fig. 3 is a central section of the razor taken transversely of theblade holder and through the handle. j i

Referring to the drawings, 1 designates what maybe termed the bladeholder, such holder being transversely curved and havingA each sideedgeterminating in a comb 2 which serves as a guard for the adjacent edge ofa blade 3 when secured to the holder. rlhe kholder l has a hollow handle4 Aprojecting centrally from its inner or concaved side, said handleforming in its outer end -portionthe chamber 5Dand in its inner end por`tion the restricted passage, 6, which opens at its inner end into saidchamber and has its outer end openingthrough the holder 1.

The blade 3 is held to the holder 1 by a clamping or holding plate 7,which is substantially co-extensive :1n length 'with .the holder 1 andhas its inner surface cuorved` chamber 5.v The free end of the stem 8,or n the portion of such stem which projects into the chamber 5, isthreaded, as at 9, to

adapt it to thread into the adjacent end. of a plug l0, which has alooseturning fit in the chamber 5 of the holder handle.

The

outer end' of the plugflO is providedwith a head or enlargement 11 whichshoulders against the outer end of thehandlel to limit the movement ofthe yplug therein, and is preferably knurled on its peripheral surfacesto facilitate a hand turning. thereof.' The..

clamping plate 7, in the presentinstancehas twoy studs 12 projectingfrom its inner slde `in position to enter registering apertures 13 inthe blade and holder .when the plate is in clamping relation tothe'holfder.

The construction so far described is the same kas that df the Grilletteysafety razor, and the plug" 10' is hollow throughout its length with itsinner end restricted and threaded to engage the stem -9 the same aslwith the Gillette construction.

In carrying out the feature of lmy invenin assembled relation, the plug11 is turned lend of the fplug 10, said stem having its inner endreducedand threaded, as at 15, to adapt it to thread into the threaded innerend portion of the plug 10, and having its other portion of a size tohave a turning fit in the'outer end portion of the plug 10.

The outer end of the stem 14 is provided with a head or enlargement'16that is preferably knurled on its peripheral surface to` stem projectingtherefrom into the handle,

facilitate a hand turning thereof.

In the use of my invention, the parts being relative tothe handle 4 tocause a threading of the same on the clamping plate stem 9 and aconsequent drawing of the plate into position to clamp the blade 7 tothe holder 1. Vhen the stem 8 has been drawn in suiciently to obtain thedesired adjustment of the blade edges with respect to the vholder thestem 14 is turned into. the plug 10 until its inner threaded end`comes'into contact' with the threaded end of the clamping plate stem 8,thereby preventing a further turning -of the plug 10 in a directiontoeffect a drawing in of the clamping plate. The plug 10 and vstem orstop, member 14 may nowbe turned together as a unit in al direction toeffect a releasing of the clamping plate 7 lfor the purpose of cleaningor replacing of the blade 3 without'losing the adjustment of the parts10 and 14. 'Upon a replacement of the blade the parts are drawn ,itopreviously adjusted position by turning .the plug 11 into ythreadedengagement with the clamping plate stem'8 until such stem moves intocontact with the stem or stop member 14, which causes a stopping of theinward movement of the clamping plate at the position of adjustmentpreviously obtained. In case both a light and close shave j to obtainthe close shaving adjustment.

are desired the stop member 14 may be set 'for the light shave and theplug 10 then turned a predetermined extent, as for instance, a quarterturn, half turn, or the like,

I wish it understood thaty my invention is not limited to any specificconstruction, ar-

rangement or form of the parts, as it is capable ,of numerousmodifications Without departing from the spirit of the claims.

` I-Iaving thus` described my invention, what I claim as new, and desireto secure by Letters Patent, is,- y

'. 1. In a safety razor, a blade holder having v comprising two membershaving their meeting surfaces curved in cross-section, one of saidmembers having a hollow handle projecting therefrom and the other havinga.

a plug rotatably projected into the outer end of said handle andthreaded at its inner end to said stem end, and a stop member rota--tably carried by said plug and threaded therein with its inner end inposition to have stop contact with said stem end.

3. In a safety razor,a blade opening part comprising two clampingmembers having -their meeting faces transversely curved to adapt themwhen drawn together against' an interposed blade to cause more or lessfieXing ofthe blade, one `of said members having a hollow handleojecting therefrom and the other having a stem which removably projectsinto said handle, a plug inserted into the outer end of the handle andhaving a turning fit therein, said plug having its inner end threaded tothe stem endv andhaving its outer end shouldered against the handle endto limit its movement intoy the handle and to facilitate a hand turningof the plug, yand a stop member projected into said plug axially thereoffor turning movements therein and having its inner end threaded into theplug in position to have adjustable stop contact with the stem end andhaving its outer end exposed without the outer end of the plug to1facilitate a turning of one relative to the other.

` 4. In a safety razor, a holder, a member for coacting'with' saidholder to clamp a blade thereto and having a stem projectedy j at itsinner end with said stem lend to limit the eXtentr'of threading bf saidmeans into the stem. j

In testimony whereof I have hereunto lsigned my name to thisspecification.

PAUL E. GLEAsoN.
